Sd card problem

[Packmiss]

I have a canon rebel t3i. I have been taking photos for about 2 months. I have a 16 gb sd card. I have 1200 pictures on it. When I go to download them only 800 show up. Then I put the card back in and I can see all the pictures... Help....

The format with the rest of the pictures may be different.
